Why wait 2+ years? Here is a chance to buy a rare – almost new – HH50 Catamaran. The ONLY one available – worldwide!

AVALANCHE is an award-winning HH50 – a blue-water capable, performance cruiser, of lightweight carbon construction, with intelligent yet simple-to-use systems, a spacious interior, and a luxurious finish. This vessel the best of all worlds, in a compact easy-to-manage package; robustly built and fully equipped to take you around the world in comfort and style.

Carbon fiber construction produces a strong, very light, extremely rigid platform for safe, fast, fun and very efficient sailing. Designed with short-handed sailing in mind, the deck layout on the HH50 has been carefully configured for ease of sailing. Though simple to sail the HH50 is far from subdued. “Raceboat in disguise” technology abounds, and equal-to-wind-speed performance is the norm.

This performance is matched with a spacious, open above decks layout, providing the perfect environment in which to live, relax and entertain. Meantime, below deck you’ll find luxurious cabins, beautifully illuminated by large windows. To port, a master cabin which occupies the full hull, providing substantial living space and storage, with a spacious head and separate shower. While to starboard one finds two comfortable guest suites, with generous heads and separate shower.

The result? A truly impressive liveaboard cruising platform! Exclusively for sale with Just Catamarans, contact us today!
